该平台利用深度学习和大型语言模型，将你的合同与由成千上万个实际协议构建的市场标准进行比对。它会突出显示潜在风险点，评分整体风险，并建议符合你设定标准的修正方案。

SpeedLegal 既适合律师，也适合非法律专业人士使用，支持超过 25 种合同类型，涵盖五种语言。法律团队、创业者、销售部门以及房地产经纪人都可以用它来审查保密协议、主服务协议、雇佣协议、SaaS合同等，无需花费数小时进行手动阅读。

CoCounsel is a legal research and drafting assistant now owned by Thomson Reuters after acquiring Casetext in 2023 for $650 million. It runs case law research, document review, contract analysis, and guided drafting grounded in Westlaw and Practical Law rather than the open web.

Standalone legal chatbots pull from generic training data. CoCounsel ties every answer to Thomson Reuters authority, which means citations trace back to Westlaw primary law and Practical Law guidance. The 2026 next-generation release adds Workspaces for matter-specific context, Brief Builder for agentic motion drafting, and a firm-intelligence layer for encoding internal expertise.

Litigation teams, transactional lawyers, and in-house counsel at firms already paying for Westlaw use it to cut research time and review contracts at scale. Pricing is sales-led with no public rate card, and the tool delivers the most value when bundled with an existing Westlaw subscription.
